Ed Miller DVD hand?

[MCS]

This is from the Ed Miller DVD on "Protecting Your Hand," which is my favorite of the four.

No reads. I assume the players are typical mediocre-poor, since that seems to be the standard NPA assumption in the DVD.

Preflop: Two limpers (L1 and L2), we raise, blinds fold, limpers call.

L1 bets, L2 raises, Hero ___?___

This is the only hand where I'm really having a lot of debate. I'm not sure if I agree with Ed's answer, though if he and I do disagree, he is a big favorite to be correct. [img]/images/graemlins/smile.gif[/img]
